Did you go to the display properties and enable the other outputs?
Well, I go into Control Panel and search for "display", one option is "connect to an external display". Go into that and click "Detect" - nothing. Same basic process within Catalyst Control Center with the same result. With Windows 7 beta 32 bit there was automatic discovery. I didn't even need to install CCC or set anything. So, the OS came with two discs - 32 and 64 bit versions. I just ordered a cheap internal HD. I will switch that in, install the 32 bit version, see what happens, and let you know.
